Takeru Utsugi: Structure of a quantum computer
Recently, as the term "quantum computer" has begun appearing in the news, even non-experts have more opportunities to encounter this keyword. Indeed, quantum computing is a highly anticipated field as a next-generation technology. However, the reality is that there are still very few books explaining the full scope of quantum computing for beginners. Unlike next-generation technologies such as machine learning, IoT, and VR/AR, quantum computing is strongly rooted in fundamental research aspects of quantum physics, information theory, and computer science. If you search for quantum computers on the internet, information is scattered here and there, and there is not much organized information available. Furthermore, news reports and explanatory articles regarding quantum computing often differ in their conceptual definitions, making it difficult to see exactly where the technology stands today. It is hard to grasp the extent to which quantum computers will be commercialized, how they operate, what methods exist, and how they differ from one another. Consequently, it is quite difficult to understand them through actual building or use. Additionally, introductory books aimed at the general public often explain quantum properties through analogies. However, they rarely provide detailed explanations that lead to the next level, leaving readers ultimately no choice but to read specialized books or academic papers. This book is structured to provide a comprehensive overview of quantum computers for those who are not physics experts and are encountering the subject for the first time. The goal was to create a book that is easy for non-experts to understand, requiring no technical jargon or specialized knowledge. It is designed to be easy to grasp through accompanying illustrations and will help visualize the operating structure.
